Although this may not directly apply to Millerelix peregrina, it was an interesting find indicating that snails can have important uses for humans besides being a meal. A study was done to test if snail shells are an effective coagulant in waste water treatment (Jatto et al., 2010). This study specifically focused on the shell of a snail from the Family Achatinidae, a family which is most commonly known to contain the African land snail (Jatto et al., 2010). The Achatinidae shell, like the shell of Millerelix peregrina, is made mostly of calcium carbonate (Jatto et al., 2010). It was found that the calcium carbonate shell helps to neutralize small dissolved particles in water supplies (Jatto et al., 2010). Effective at any PH, these shells successfully reduced many chemicals in the waste water, such as sulphates and nitrates (Jatto et al., 2012). There was also a complete removal of excess phosphate from the water (Jatto et al., 2010). The use of snail shells in water treatment could possibly be applied to other species of snails including our very own Millerelix peregrina! The use of snail shells in water treatment could be economically efficient and very beneficial for humans (Jatto et al., 2010).
